Emerald
iOS and Android apps that monitor air parameters






About the app
Emerald is the ultimate tool for monitoring air parameters at home. Emerald Air app gathers data from Emerald devices using Bluetooth Low Energy and lets you inspect air quality, temperature, humidity and pressure from multiple devices at once.
The system will notify you when air parameters are not within acceptable range and will offer useful tips on how to improve them as well. Built-in graphs and stats let you track changes live as well as review historical data.
